Your friend shivers and says, "I'm so cold!" You decide to help them right away. Select ALL the grammatically correct spontaneous offers that apply.
The correct answers are I will close the window. and I'll make you some hot tea.
For spontaneous decisions and offers made at the exact moment of speaking, we use "will" (or its contraction "'ll") + the base verb.
"Going to closing" has an extra "-ing" and sounds unnatural for a sudden offer, while "will to make" incorrectly adds the word "to" after a modal verb.
